A band of pirates led by Dirk Redmond rob a luxury ship owned by the Axe-Man and make off with a box full of diamonds. A sea monster causes the pirates to land on Monster Island while their boat is wrecked beyond repair. Raptors attack them on the beach and they are almost out of ammo when Shanna shows up to save the day. Shanna takes the crew to her jungle home and they observe the Axe-Man landing a sea plane on the island as he has come looking for his loot.
